      <p> 
        Two new functions have been added to the API that perform
        hotbackups, <a href="../api_reference/C/envbackup.html" class="olink">DB_ENV-&gt;backup()</a> and <a href="../api_reference/C/envdbbackup.html" class="olink">DB_ENV-&gt;dbbackup()</a>. <a href="../api_reference/C/envbackup.html" class="olink">DB_ENV-&gt;backup()</a> creates
        a hotbackup of all databases in the specified environment, and
        <a href="../api_reference/C/envdbbackup.html" class="olink">DB_ENV-&gt;dbbackup()</a> creates a hotbackup of the specified database.
        The functions <a href="../api_reference/C/envset_backup_callbacks.html" class="olink">DB_ENV-&gt;set_backup_callbacks()</a> and
        <a href="../api_reference/C/envset_backup_config.html" class="olink">DB_ENV-&gt;set_backup_config()</a> can be called to customize the behavior
        of hotbackup. Note that this interface must be used to create
        a hotbackup on all non-BSD or Unix based systems.
